An AQMesh air quality monitoring sensor was installed at a monitoring site in East Hartford, Connecticut to evaluate its performance tracking gas, particulate and meteorology data over a year long time frame. Hourly data for O3, NO2, PM2.5, PM10, temperature and relative humidity were compared to reference monitors located at the same site. The full downloadable dataset used is located here Download CSV.

AQMesh hourly data for O3, NO2, PM2.5, PM10, temperature and relative humidity were compared by quarter to reference values (Q1: January-March, Q2: April-June, Q3: July-September, Q4: October-December).
*Outliers were defined from the AQMesh dataset using the IQR Method (all data points more than 1.5 below the the lower bound quartile or above the upper bound quartile).
